Reinstalling the controller

After you replace a component within the controller module, you must reinstall the controller module in the system chassis and boot it to a state where you can run diagnostic tests on the replaced component.

Steps

If you are not already grounded, properly ground yourself.

Align the end of the
controller module with the opening in the chassis, and then gently push the
controller module halfway into the system.

Note: Do not completely insert the controller module in the chassis until instructed to do so.

Recable the system, as needed.

If you removed the media converters (SFPs), remember to reinstall them if you are using fiber optic cables.

Complete the reinstallation of the
controller module:

The controller module begins to boot as soon as it is fully seated in the chassis.
Be prepared to interrupt the boot process.

With the cam handle in the open position, firmly push the controller module in until it meets the midplane and is fully seated, and then close the cam handle to the locked position.

Attention: Do not use excessive force when sliding the
controller module into the chassis; you might damage the connectors.

Tighten the thumbscrew on the cam handle on back of the controller module.

If you have not already done so, reinstall the cable management device.

Bind the cables to the cable management device with the hook and loop strap.

As each node starts the booting, press Ctrl-C to interrupt the boot process when you see the message Press Ctrl-C for Boot Menu.

Select the option to boot to Maintenance mode from the displayed menu.
